• Visual Studio macro to build MSI project - get popup when I set Version property

  OK, I've written a macro to build a MSI project, incrementing the version and setting the productcode GUID. However, as soon as I set the Version property I get a popup saying "It is recommended that the ProductCode be changed if you change the version. Do you want to do this ". I run this macro from the command line as part of an automatde build but this popup stops the build. It didnt do this in VS2003, but it does in VS2005. Any solutions: ways to suppress popups, or anything else Order doesnt seem to matter (ie version before ProductCode or after) Code: Dim prop As EnvDTE.Property Dim propVersion As EnvDTE.Property ' get the project version property propVersion = GetPropertyByName(proj.Properties, ...Show All

• SQL Server Upgrade from 2.0 to 2005 Notification

  I'm trying to upgrade from Notification services 2 to 2005 and am having some problems. I have run: nscontrol upgrade ..... and the system reported a successful upgrade, however when I run: nscontrol status... I get: Database version: 2.5.0.1 Assembly version: 9.0.2047.0 I'm under the impression the upgrade did not work. If I try a nscontrol export, I'm getting the error that the instance can't be exported because the database version does not match the assembly version. Any ideas thanks! After performing the nscontrol upgrade, you will need to run nscontrol update before the upgrade is considered complete. Please see the instructions for the upgrade process in Books Online. ...Show All

• Audio and Video Development Tee node and custom media source

  I used the WavSource MediaSource example and I used it in topology using a tee node. When I do that, an errors occurs after starting the session (0x8000FFFF). If I dont use a tee node everything works fine. I tried setting the MF_TOPONODE_PRIMARYOUTPUT and MF_TOPONODE_DISCARDABLE but that did not change anything. Marc I just tried out your test application and, well, WAV files play just fine for me. Since you're most likely talking about RC1, and I'm running a newer build, I'd like you to try this again with the next SDK version that comes out and let me know if you're still running into this problem.

• Software Development for Windows Vista How to append data?

  I'm trying to write two sets of files to a data disc in separate recording sessions. I'm getting an IMAPI_E_IMPORT_MEDIA_NOT_ALLOWED error from IFileSystemImage::put_MultisessionInterfaces the second time I try to write files, but I'm sure I'm not doing something correctly. (The media is DVD-RW). What is the correct procedure for appending files to a data disc So how do you actually append data to supported media (CD-R/RW, DVD-/+R) I'm assuming you have to call IFileSystemImage::put_MultisessionInterfaces; but how do you get the SAFEARRAY list of multi-session interfaces in the first place Do you call CoCreateInstance to create a IMultisessionInterface object first and then build a SAFEARRAY from scratc ...Show All

• Visual Studio 2008 (Pre-release) DirectionalLight and different materials

  Hi! I am trying to make an animated 3D model of the solar system. I am having problems with lights and materials. Is it possible to make a object that emits the light (directional) For now I am using only sun and earth. I am using DirectionalLight to make earth visible but I don't want the sun to be enlightened by that light. If I use only EmissiveMaterial for the sun it looks OK, but when the earth should go behind the sun it appears in front of it. Is this a bug It looks like a bug. If I change only the material of the sun the earth goes behind it as it should. But DiffuseMaterial is enlightened by directional light and it does not look like the sun any more. Does anybody have an idea how could I achieve the proper li ...Show All

• Software Development for Windows Vista Regd SubType for 48-bit RGB

  Hi All I'm now working with Source Filters.Direct Show Filters support bitcounts upto 32.There is no support in direct show to handle Images of bitcount greater than 32.I need to handle TIFF Images of BitCount 48. I did the code to output the stream of Image data to Transform Filter/Renderer Filter.But it doesn't work b'cos there is no subtype to handle 48-bit RGB. Can anybody tell me how to make a Transform/Renderer filter to handle 48-bit RGB OR Any other possible ways to do it.
